This landmark event confirmed both the association of some GRBs with compact binary mergers, and that neutron star material can be ejected in sufficient quantities to power a detectable radioactive transient. It opened a new window on long-standing problems in astrophysics, cosmology and fundamental physics, including the possibility that BNS and NSBH compact binary mergers are the dominant source of heavy r-process elements in the universe. However, the lack of success in identifying similar events in the O3 and O4a runs of the gravitational wave detector network highlighted that their rate is low in the nearby universe (e.g. z<0.1), thus opportunities for study of the kilonova population, crucial to understanding their range of behaviour and heavy element yields, for example, will be infrequent. Here we propose a ToO campaign to follow the light curve of a kilonova discovered during cycle 32, coincident with a well localised GRB at 0.1<z<0.4 but not a GW signal (which are the target of other proposals). HST has already made unique contributions to the follow-up of AT2017gfo and its off-axis relativistic jet, and also provided the primary evidence for the most compelling cases of KNe following short-GRBs. Our HST+XMM program is flexible to adapt for different possible scenarios, and will be crucial for understanding the diversity of EM emission from neutron star compact binary mergers, and providing the data to test increasingly sophisticated KN models. We intend to conduct comprehensive Optical to IR observations of a kilonova associated with a low redshift GRB, spanning four epochs (the last being a late time visit after the transient light has faded). This will include early UVIS and IR imaging with a range of three filters chosen at trigger time according to information available from early ground-based imaging. Given the uncertainty in the field due to the limited number of detections we specifiy a range of possible observations, as explained in our phase I, which are described below. However, it will be necessary to update the phase II at the time of the submission. To avoid a very crowded phaseII we do not include copies of all individual observations, and will duplicate to request multiple repeats of the same ones (which we will copy to a new phase II at the time of trigger). The observations specified are: U1 - 1 orbit F475W U2 - 1 orbit F555W U3 - 1 orbit F606W U4 - 1 orbit F814W U5 - 1 orbit F850LP M1 - 1 orbit F475W/F606W/F814W M2 - 1 orbit F606W/F140W M3 - 1 orbit F105W/F160W I1 - 1 orbit F105W I2 - 1 orbit F110W I3 - 1 orbit F125W I4 - 1 orbit F140W I5 - 1 orbit F160W NB. We have specified both disruptive and non-disruptive turn-around times in the on-hold OBs, and will set the appropriate timing at trigger time. The final (4th) visit, and possibly the 3rd, will not be included in the disruptive activation. Our team has a great deal of expertise in observations of gamma-ray burst, supernovae and gravitational wave counterparts. We led the first HST observations of the counterpart of GW170817 as published in numerous papers (e.g. Tanvir et al. 2017 ApJ 848 17, Levan et al. 2017 ApJ 848 18, Hjorth et al. 2017 ApJ 848 28, Cantiello et al. 2018, Lyman et al. 2018 Nat As 2 751, Lamb et al. 2019 ApJ 883 48).; and also prior HST studies of kilonovae associated with SGRBs (e.g. Tanvir et al. 2013, Lamb et al. 2019b). Most recently, members of our team have been amongst those demonstrating the existence of a merger origin for a fraction of long-GRBs at low redshift. This proposal is from a large international collaboration that contains members operating major GRB follow-up campaigns from 2-8m ground telescopes. Our collaboration also includes significant expertise in theoretical interpretation. It contains a mixture of faculty, postdoctoral and student members and training is an important element of the programme. This ensures we have both the expertise and the resources to undertake these observations.
